ABSTRACT

The psoas abscess during puberty without trauma is not frequent. In this occasion the evolution and treatment response of a case of abscess of the psoas due to Staphylococcus aureus (STAPH) and a review of the literature is reported. A twelve-year-old female without a significant pathological history, except for carrying a heavy backpack. Ten days before admission history of progressive lumbar and sacral pain, mainly on her left side with practically no response to nonsteroidal anti-inflammatory drugs, radiation to the left limb, limitation of the left hip movement and limping. The pain increased during movement and position changes. On the eight day 39.5°C fever was added to the symptoms. Positive blood cultures to STAPH were obtained. During the magnetic resonance imaging a mass was found of 4 x 5 cm on the left psoas muscle in its superior third with central necrosis. Surgical drainage was preformed and a drain was inserted. Clinical recovery was shown 48 hours after surgical and antibiotic treatment. The course was uneventful. The recommendation regarding Back Pack safety is that students should not carry more than 10-15% of their weight. Psoas muscle abscess diagnosis is very difficult to make, image studies are useful in diagnosing this condition. Pyogenic psoas abscess is a primary condition caused mostly by STAPH.
